TYPE-CLEANING DEVICE FOR TYPE-WRITERS.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed February 9, 1906. Serial No- 300,285.

To all whom it may concern:

Be it known that I, DANIEL Bnroes, a citizen of the United States, and aresident of the borough of Brooklyn, city of New York, in the county ofKings and State of New York, have invented certain new and usefulImprovements in Type-Cleaning Devices for Type-Writers, of which thefollowing is a specification.

My invention relates to type cleaning devices for typewriting machinesand has for its object to provide a simple and efficient device of thecharacter described and which may be readily attached to and detachedfrom a typewriting machine.

To the above and other ends, the invention consists in the features ofconstruction, combinations of devices and arrangements of partshereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical longitudinalsectional view of a typewriting machine showing my invention adaptedthereto, parts of the machine being omitted. Fig. 2 is an enlargedsectional view of the type cleaning device and a part of the frame ofthe machine, the section being taken transverse of the machine, and theparts being shown in inoperative position. Fig. 3 is an enlarged frontelevation of the type cleaning device, the parts being shown inoperative position. Fig. 4 is an enlarged top plan view of a parthereinafter called the brush head, the support thereof being shown intransverse section. Fig. 5 is an enlarged detail view in horizontalsection showing the connection between the brush frame and the actuatinglever therefor.

Referring more especially to Fig. 1, 1 indicates the side portions ofthe base frame, said side portions being connected by front and backtransverse portions 2. Corner posts 3 rise from the base and support atop plate 4 on which is secured a circularly disposed set of type barhangers 5 pivoted'in which at 6 are type bars 7, said type bars beingconnected by links 8 with key lovers 9 fulcrumed at 10 in the rear ofthe base, and each provided with a restoring spring 11. The normalpositions of the type bars and their actuating devices are shown in fulllines in Fig; 1. The type bars carry type blocks 12 at their free endsand normally lie against a type rest 13 fixed below the top plate of themachine. Said type bars are adapted, when their associate key levers areactuated, to be swung upward, as indicated by the dotted lines in Fig.1, to cooperate with the bottom of a cylindrical platen 14diagrammatically illustrated.

Referring now to the type cleaning attachment, I

' provide a supporting bracket comprising two parts, a

' latter being perforated to receive a pivot rod 18 by which the part 15is connected with the other part 19 of I the bracket (Figs. 1, 2 and 3)which is likewise preferably made of sheet metal. Said part 19 isvertically disposed between the ears 17 of the part 15 and is broadenedout at its lower end, terminating in a hook portion 20 and beingprovided at the sides with stiffening flanges 21. The part 15 of thebracket is provided with a boss 22, said boss being formed with athreaded opening which receives a thumb screw 23 for securing thesupporting bracket in place. The end of the screw 23 is adapted toengage with a spring-plate 24 which is formed with a shoulder 24 andsecured to the under side of the part 15 of the bracket by headed screws25. The spring plate serves both as a protector and as a lock, in amanner presently to be described. Near its inner or free end the part 15is provided with a thread ed opening which receives the lower threadedend 26 of a vertically disposed supporting rod 27, the thread ed portion26 beingof reduced diameter and forming a shoulder 28 with the bodyportion of the rod, said rod being screwed down until the shoulder abutsagainst the top of the part 15. A locking nut 29 engages the threadedportion 26 and is screwed up against the under side of the part 1.5,thereby serving to secure the rod 27 fixedly to said'part 15. The sidesof the supporting rod 27 are flattened, as indicated at 30, shoulders 31being formed on the rod 27 where the flattened portions 30 terminate,said shoulders serving as stops in a manner presently to be described.Loosely and slidably mounted on the support or rod 27 is a sleeve 32,said sleeve being squared at its upper part as indicated at 33, thesquared portion forming, at its junction with the body portion of thesleeve, a shoulder 34. The upper portion of the squared part 33 isrounded and externally threaded as indicated at 35. The squared portion33 receives a conical brush head 36 which is formed with a squareopening 37, said square opening cooperating with the squared portion 33of the sleeve 32. The head 36 is provided with bristles, some extendingdownwardly and some inclined downwardly and laterally, said bristlesforming a downwardly disposed conical cleaning brush 38, which surroundsthe sleeve 32 below the brush head 36. A thumb nut 39 cooperates withthe threaded portion 35 of the sleeve to clamp the brush head againstthe shoulder 34, thereby maintaining the brush in fixed relation withthe sleeve. Below the brush the sleeve 32 is provided with twooppositely disposed horizontal slots 40, said slots being cut insulficiently deep to penetrate the bore of the sleeve and expose thesupporting rod 27 within said sleeve as indicated in Fig. 3. Secured tothe part 15 by headed screws 41 is a small substantially U-shapedsupporting bracket 42 preferably made of sheet metal and pro vidcd withvertically disposed ears 43, said ears receivin g a pivot rod 44. Therod 44 serves as a fulcrum for a sheet metal actuating lever 45, saidlever being provided at its outer end with a finger piece 46 and havingat each side stiffening flanges 47, each flange being shaped to form anose 48 below the fulcrum 44. The inner end of the lever 45 isbifurcated, the arms 49 of the bifurcation entering the oppositelydisposed slots 40 in the brush sleeve 32 and thereby loosely connectingthe sleeve with the lever. A flat locking spring 50 is secured to thetop of the part 15 by means of the screws 25 and the free end of saidlocking spring is adapted to cooperate with the noses 48 on theactuating lever 45.

Referring now to the mode of attaching and operating my improved typecleaning device, it will be understood that said device is attached toone of the side portions 1 of the base of the machine, the part 19 ofthe supporting bracket being swung about its pivot 17 until the hookportion 20 engages the bottom edge of the side portion 1. The thumbscrew 23 is then screwed down tight to clamp the two-part bracket inplace, the spring plate 24 being interposed between the end of the screwand the top flange 1 of the side portion 1, and thereby preventing saidside portion from being marred by said screw. The angular shoulder 24*of the spring plate abuts against the top flange 1 and prevents thebracket from being accidentally displaced laterally outward. Furthermorethe spring plate tends to draw the hook 20 up against the part 1 to lockthe bracket in place. When properly secured in place the part 15 of thesupporting bracket extends inwardly towards the middle of the machineabove the key levers 9, passing between two of the links 8 and being sodisposed as not to interfere with any of the working parts of themachine. It will be noted that the two parts 15 and 19 of the supportingbracket form a knuckle joint, the top of the part 19 abutting againstthe under side of the outer end of the part 15 (Fig. 2). This abuttingengagement of the parts is at the opposite side of the pivot 18 from thescrew 23, so that when said screw is tightened the bracket as a whole iselevated, drawing the hook 20 up tight against the bottom of the sideportion 1. The castings of machine frames are found in practice to varyin dimensions; but my construction is such that though the depth of theside portion may vary considerably, yet the two part brackets mayreadily be attached thereto. ,The machine illustrated is the Remingtonand my attachment is particularly adapted to the Nos. 6, 7, 8 and 9Remington, but, of course, may be constructed to be applied to othermakes of machines. The supporting rod 27 is secured on the part 15 ofthe bracket in such position that when said bracket has been secured inplace as described, said supporting arm will be vertically disposedabout centrally of the type basket. The inoperative position of theparts is shown in Fig. 2 and in full lines in Fig. 1. In this positionthe bottom of the sleeve 32 is in contact with the top of the part 15,the conical brush 38 being lowered out of the paths of the type blocks12, as will be understood from a consideration of Fig. 1. When it isdesired to clean the types, the finger portion 46 of the lever 45 isdepressed, thereby raising the inner arm of said lever and causing thearms 49 of the fork or bifurcation at the end of said lever to raise thesleeve 32 and the brush sure exerted by the operator, but as soon as thespring contact passes from one side of the noses to the other, thepressure of said spring will be reversed and it will tend thereafter tolift the type brush. The upward movement of the brush continues untilthe inner edges of the arms 49 of the actuating lever engage with theshoulders 31 on the supporting rod 27, thereby preventing furthermovement upward. The brush will be stopped in the position indicated infull lines in Fig. 3 and in dotted lines in Fig. 1. If now the severalkey levers be depressed, their associate type bars will be swungupwardly from normal position until the type blocks are arrested by thecleaning brush 38. As will be understood from a consideration of Fig. 1,the bristles of the brush are arranged substantially perpendicular tothe face of the types so that the ends of said bristles may readilypenetrate the depressions in the types and clean them out. The arms 49of the lever 45 closely embrace the slotted portion of the sleeve 32, aswill be understood from a consideration of Figs. 1 and 5, so that saidsleeve is held from rotation and consequently the type brush 38 isprevented from rotating. This construction provides a non-rotatingbrush, the bristles of which are presented squarely to the types so asto obtain the most advantageous cleaning effect from said bristles.While I prefer to employ a non-rotating brush, it is to be understoodthat some of the constructive features of my invention are notrestricted to non-rotating brushes.

When it is desired to restore the parts to inoperative position, theoperator presses upwardagainst the under side of the finger portion 46of the lever 45, the locking spring 50 acting against the pressureexerted until the dead center is again crossed, after which it willassist in lowering the brush until the end of the sleeve 32 againcontacts with the arm 15 of the supporting bracket.

Various changes may be effected without departing from the spirit andscope of my invention.
